Nothing stops Foreign Affairs Minister Nkosazana Dlamini-Zuma from standing for more than one position, according to the ANC.
Her office also indicated that she would not publicly declare her preferred position.
Party spokesperson Tiyani Rikhotso said that it was up to Dlamini-Zuma to choose which position she preferred.
Dlamini-Zuma has been nominated for the party's deputy presidency by four provinces aligned to President Thabo Mbeki, while the five provinces backing her ex-husband ANC deputy president Jacob Zuma prefer her as the national chairperson.
"A candidate can be nominated for more than one position. She can also approach the Electoral Commission and inform them which position she chooses. It's up to her," said Rikhotso.
Dlamini-Zuma finds herself caught in the middle of the tug-of-war between her employer Mbeki and the father of her three children Zuma.
The Zuma camp has given her an ultimatum to choose between them or Mbeki.
But a source close to her said that her children could largely influence her decision as they had previously persuaded her not to accept the deputy presidency - first offered to her by Mbeki after he fired Zuma in 2005.
The deputy presidency position was then offered to the incumbent Phumzile Mlambo-Ngcuka.
The lady in the middle has so far chosen to duck the issue, opting to give the ANC's official line: "A comrade does not choose where they want to go, you listen to the people."
Her spokesperson Ronnie Mamoepa said that Dlamini-Zuma would not publicly declare her choice. "That answer will go to the ANC's headquarters," said Mamoepa.
KwaZulu-Natal ANC Youth League chairperson Nhlakanipho Ntombela said that they were hoping that Dlamini-Zuma would accept the Zuma camp's offer.
Dlamini-Zuma is currently overseas and is due back in the country on Thursday. - Political Bureau
